Example 2: stringstream in c++

std::stringstream os;
os << "12345 67.89"; // insert a string of numbers into the stream

std::string strValue;
os >> strValue;

std::string strValue2;
os >> strValue2;

// print the numbers separated by a dash
std::cout << strValue << " - " << strValue2 << std::endl;
